Linux got me a job later on in life. Made my life a breeze honestly.
I know most people will talk about how Linux/Windows/Mac but one of the not often talked about benefits to learning an OS really well is that it can lead into a high paying job. And Linux allows you to see under the hood as deep as you want....so more likely.
Price point of 36 is pretty good.
I personally would just spend 10$ more on a mini UPS if I was looking for battery backup as you get way more battery and can work with just about anything. Or a real UPS for 15$ more that can work with multiple devices and a battery that would probably last a pi for a good day.
